Phil, Thanks,
"I would presume that if you pinged the machine you would get the old address as well." You are exactly right. It resolves to the old ISP address "Look at the box you are doing the testing from and make sure it has correct DNS servers." The machine I am testing from is the mail server itself. The contents of /etc/resolv.conf is 127.0.0.1 "The nslookup may not be using the same DNS as the box." When I test at the nslookup prompt and type the FQDN of my mail server it resolves correctly and uses 127.0.0.1 as the non-authoritative server. What I don't understand is which servers would telnet and ping be using? "lserver command" This application is not on my Linux box. Yum doesn't install it either. Any suggestions. I'll send you the info you requested privately. Finally, shouldn't the settings have propagated throughout the internet, and shouldn't telnet and ping use the contents of /etc/resolv.conf to resolve FQDN's?

Look at the box you are doing the testing from and make sure it has correct DNS servers. The nslookup may not be using the same DNS as the box. It usually does but you can change it with the "lserver" command. I know you don't want to put the names and IPs on the list but if you want you can contact me off list with that info and I'll be glad to check it out for you.
